EYELETIVNG OR` RIVE'IING IMPLEMENT Filed July 20. 1935 vIl Patented July 21, 1936 nire stares EYELETING R RIVETING IRIPLEMENT Edward L. Sibley, Bennington, Vt., assignor to Edw. L. Sibley Mfg. Co., Inc., Bennington, Vt., a corporation of Vermont Application July 20, 1933, Serial No. 681,377

20 Claims.

The object of this invention is to provide an implement o-f the plier type by means of which a variety of eyelets or rivets may be set, and in some instances re-formed or reverted into substantially their original shape for further use, and in some instances converted into double open-end type for ribboning and other purposes, and in some instances removed by suiciently turning the same inside out.

Illustrating the use of the invention, two types of eyelets are shown, first, one having one end closed and the other open and provided with a circumscribing laterally projecting flange, the barrel or shank of the eyelet being longitudinally partible between the two ends so as to collapse in setting and thereby form a laterally extending head in substantial parallelism with the said flange in order to grip opposite sides of an article on which the eyeletis set, examples of vwhich are shown in patents to E. L. Sibley, No. 358,225, dated February 22, 1887 and to the undersigned No. 1,469,757, dated October 2, 1923, No. 1,611,288, dated December 21, 1926, and No. 1,615,048, dated January 18, 1927, and, second, the ordinary eyelet which is open at both ends. The invention, however, is not limited to any specic type of structure of the eyelet or rivet, excepting as hereinafter claimed.

The invention consists of an implement or tool having pivotally connected crossed handles carrying in always parallel relation a punch and a die with automatic means for aligning these parts for the purpose of setting the eyelet or rivet, for removing it, for converting it into a ribbon-receiving fastener, and for reverting or redeeming it for the addition of more parts to be fastened, as I will proceed now more particularly to set forth and finally claim.

In the accompanying drawing illustrating the invention, in the several gures of which like parts are similarly designated, Figure 1 is a side elevation of the implement in normal open position with one handle partly broken out. Fig. 2 is a longitudinal section with the handles partly broken away, the position of parts being the same as in Fig. 1. Fig. 3 is a longitudinal section, the handles being partly broken away and the punch and die elements being closed as in the punching act. Fig. 4 is a longitudinal section with the punch elements shifted and in locked position so as to operate against the upsetting anvil when the jaws are closed to setthe eyelet. Fig. 5 shows the parts of Fig. 4 in upsetting position. Fig. 6 is a detail illustrating a movable die placed in operative position when it is desired to redeem a set eyelet for the addition of more parts to be fastened. Fig. 7 is a perspective View of one form of eyelet or rivet which the implement is designed to set, and Fig. 8 is a top plan view of the eyelet or rivet of Fig. 7 set. Fig. 9 is a fragmentary 5. longitudinal section of a modified form of upsetting anvil to adapt the implement or tool for setting ordinary commercial open-end eyelets such as shown in elevation in Fig. 10 and in cross section in Fig. 11, the latter View showing the eyelet lo set.

While the invention is illustrated in a form of a hand-operated implement or tool, it may beincorporated, with any necessary changes, in a power or other press or machine.

The die member includes a part I which is mounted in a handle member 2 at one end and a handle member 3 at the other end. 'I'hese handle members are crossed and pivotally connected at 4 and provided beyond such pivots with :jaws 5 and 20 6, respectively.

The die member I is in the form of a channel, and this channel is connected at its rear to the handle 2 by a bolt I sliding in slots 8 and secured in the handle, so as to permit the opening and closing movements of the handles, and it is pivotally connected at its forward end to jaw 6 by a bolt 9 crossing from side to side of the channel in such way as to permit the jaw 6 to turn thereon as the handles are opened and closed. In the forward end of this channel is mounted the die proper I0 which lls the inside of the channel at the forward end and is held stationary therein by a rivet I I headed up in the side walls of the channel. I2 is a pin mounted to slide longitudinally in a through hole in the die proper and held therein by means of a spring I3 attached to the channel.

'I'he die proper or anvil I0 may have pivoted to it a movable die I4 capable of being turned out of position as shown in Figs. 1 to 5 and 9, when not needed for use and to be turned into useful position as indicated in Fig. 6, when needed, as will presently appear.

A retractile spring I5 is secured at one end I6 within the handle 2 and at its other end II it is connected with the rear portion of the channel of the die member, so that the effect of the spring is to separate or open the jaws of the implement or tool.

The punch includes a channel member I8 provided with slots I9 on opposite sides through which slots extends a bolt 20 near the rear of the channel, said bolt being secured in the handle 3. Near the front of the channel this punch member is supported by a bolt 2l passed transversely through the jaws 5 of the handle 2. The punch 22 is mounted in a block 23 having a longitudinal sliding motion in the channel i8 and provided with a by-pass cut 24 to overlie the bolt 2 I. Y The the channel by means of a spring 2 anchoredat vone end 28 to the channel and at the other end 29 to the block 23, so that 5in normal open position the punch 22 rests upon the bottom of.

the channel and is thus supported in operative position. A slot 30 is provided in the bottom ofthe channel to expose a portion of the head of the punch 22 and this head rests upon a at spring 3| to `aid in keeping said punchnormally projected.

1n the channel I8 is mounted on' a shaft'32"a plane elliptical *cam '33 having truncated Aends and provided with a `series of equidistant pins, eX- trusions or 4other .projections 3 extending parallrel tothe cam axis from one side thereof. y This cam is arranged so as to have its peripheralsurfaces turned into engagement with'the block 23 to permit the movement of said block into and out of position and `also to hold it in lgiven position.

The parts i3d are successively engaged by a hook parts `3Ilxin the .cam Lby. rneansof aspring '31,

coiled around the pin '35' andV having one'end abutting against the channel member I .and the other endlying upon the back of the hook.' 'The cooperative'arrangement of the hook or vpavvl 35 and the `elliptical cam '3?3 may be .so modified, if desired, that the `hook or pavvl instead of engaging pins 34 or other offstanding parts carried by the cam may engage iin .holes or `depressions in the cam for imparting movement thereto 'as the hook or `pawl returns :toits original position. .Such .a modication .may readily be made by twisting the shank of the hook :.or pawl in such manner that the operative hook-like end of same will lie in substantial parallelism Ywith the axis 22 and the pin I2 in this position are in align.

ment, so that when the handles are moved 1toward each other, the 22 and its'supported eyelet vare moved toward .the die I@ and 'the eye,- let tis'forced through the article to be Vfastened,

vtheipin I2 being 'movedupwardly against tension of its spring I3, and lthen pressure Von the handles rbeing relaxed, the cam is moved from a position shown :i-n Fig. 2 to the position shown 'in Fig. f4, the spring '2l `then pulling the block. 23 and lits .punch member 22 into a'positi'on out of 'ali'gnm'entwith `thefpin I2 and'into a position opposite the portion I0 of the die, and then moving the i handles toward feach Zother againthe eyelet is forced into conta-'ct `with the portion I 'and colflaipse'd.as.indicated in Fig. Y8, the collapsed 'head being on, the topsideof. the article to be fastened opposite'to the-flange and the eyelet thereby "set,

' pressure'uponthe handles.

setting the eyelet. After the eyelet has been forced intoYV the article on which it is to Vbe setV .and the pressure on the handles is relaxed the 2, ready .to receive another the block 23 outwardly shifts the support of the 'punch 22 to the bottom of thechannel so as to Y hold the punch solid against the pressure used in partsare'moved into the'positions shown in Figs. s v

4 and i5 and the punch is thus moved opposite the slot 3i! and rput under the tension of the spring 3i so that the punch may recede (see Fig. 5) as said eyelet is upset against anvil VI@ and permit the removal of the yarticle -containing the set eyelet and then forwarded to the position f shown in Figs. 1, 2, and 3 `ready for. use for the in'- ser-tion of another eyelet. Y

In .these .motionsthe hook engages successivel-y with the pinsel! or other -describedparts of .the .cam so as to cause the cam to permit the sliding movement of block 23 and alternately. to hold such Vblock in; iixed position for' the time being. .l

The channel members I and I8 are mounted in the handles in parallel relation and themselves have no motion independent of the handles; their functions primarily being to carry'or support the .punch and die.

As thus far described, the 'mechanism isr useful for :operation upon'headed eyelets `or rivets; in other Words, on eyelets or rivets having -one end closed, as lshown in Figs. 7 and 8. Foroperation on commercial eyelets open at Vbothends, as shown inFigs; -10 and Ll, the die member may have a teat l38, Fig. 9, in the form of a small inverted idome .of slightly larger diameter than the inside diameter. of the Vcommercial eyelet and adapted to turn or curl over the leading Vend to eifect a setting of the eyelet, as indicated in Fig. 11.

In .setting 5a headed :eyelet (Fig. '7) the .eyelet eyelet .and the handles closed down, so that the punch and. its supported reyelet will 'be driven through the article, see Fig.Y 3,; Vthen ythe handles are released and the hook 35 on its consequent upwardY motion engages Yone of the cam parts 3H and turns the :cam from the block locking position, Figs. 2 and '3, into the block Vreleasing position, Fig. 4, and then said block retreats and brings its punch from beneath the pin I2 to beneath the part. I0, Fig. 5, lby which motion the eyelet and `the article through which the eyelet hasibeen driven are in position for another closing of the jaws, with the result Vthat the barrel or shank of the eyelet or rivet is collapsed and `the fastening consummated. During this period of heading up ,the eyelet the cam 33 has been turned `broadside :against the block 23, as in Fig. '5, and the block held in stationary position and yin 'readiness to .bereleased upon relaxingthe '.Ifzit be vdesired .to -cut .an opening in thehead roi of the set rivet for purposes of ribboning together the parts of the article, the implement or tool when again in the position shown in Fig. 1 may be given a further pressure which will operate to cut a hole in the head.

If for any reason, as for adding other parts to be riveted, it be desired to restore the shank or barrel to substantially its original shape, this can be accomplished by turning the movable die I4 into the position shown in Fig. 6 with the hole 39 therein registering with the through hole in the anvil block, and then placing invertedly the article withV the set eyelet between the dieV and punch with the punch registering with the hole 39 and the through hole in the anvil block, and then by closing the jaws the shank or barrel of the rivet will be restored to its elongated position, and then theV additional article or articles be applied and the same eyelet be used, and clinched in the same way as a fresh eyelet, onto the thus increased thickness of the article. This operation is herein referred to as redeeming the eyelet.

Details of construction may be varied within the principle of the invention and the scope of the claims following.
